Data Flash log parameters - documentation does not match data


I switched from APM to Pixhawk 2.4.8
When looking at the dataflash log the parameters does not match the documentation.
For example there are 12 parameters in the CTUN part:

And in the documentation:

There are only 9
CTUN (throttle and altitude information):

ThrIn The pilot’s throttle in as a number from 0 to 1000
SonAlt The altitude above ground according to the sonar
BarAlt The altitude above ground according to the barometer
WPAlt The desired altitude while in AltHold, Loiter, RTL or Auto flight modes
NavThr Not used
AngBst Throttle increase (from 0 ~ 1000) as a result of the copter leaning over (automatically added to all pilot and autopilot throttle to reduce altitude loss while leaning)
CRate Accelerometer + baro climb rate estimate in cm/s
ThrOut Final throttle output sent to the motors (from 0 ~ 1000). Normally equal to ThrIn+AngBst while in stabilize mode.
DCRate Pilot desired climb rate in cm/s

This mismatch is through out the log file, AHR2 is not showing in doc. and so on

where can I find the write documentation for the pixhawk
